Underwood gave her first interviews since the fall on Thursday. The singer said she landed on an area around her mouth.

"For a while, I was worried he would be scared of me," Underwood said on "The Bobby Bones Show" podcast about her 3-year-old son, who she shares with husband Mike Fisher. "But now if I put makeup on, he's like, 'Mommy, your boo-boo's all gone.'"

She said on the podcast and in an interview with host Storme Warren on SiriusXM's The Highway channel that she fell while taking her dogs out at night.

"I was clumsy and I tripped," she told Warren. "I held onto the dog leashes in my left hand and went to catch myself with my right and just missed the step. If I had fallen anywhere else, I would have been absolutely fine."

She continued, "I thought I just busted my lip. Then I walked inside and took the dog leashes off and took my coat off and went to go survey the damage and was like, Oh, no!" she said, adding, "It wasn't pretty."

The "Blown Away" singer said she also chipped a tooth but that mostly her skin was damaged.

"I felt like we put a memo out to the fan club," she said. "Just because I was like, man, somebody's gonna catch me at the Kroger. I'm gonna be buying groceries and somebody's gonna like post something on Instagram and people are gonna be like, 'What's going on?'"

"I've been very fortunate in the healing process," she said on the podcast. "I was lucky that when it happened, everything was kind of shutting down in the music world and we had the holidays and stuff like that. I was at a point where I didn't know how things were going to end up. I didn't know what was going to go on. I didn't know what it was going to heal like."

Underwood said on the SiriusXM show that the hardest part of her recovery was dealing with a broken wrist.

"I can't use my appendage and I'm trying to pick my kid up and make food and do mom stuff," said the singer, who now has a metal plate on her wrist.
